err thought the filename was changelog... change it to changelang... You should really try and figure this stuff out yourself... ur never going to learn if u cant figure this stuff out.
Of course i see what you put changelog, but still dont work with the original file, check: mimp3.net/changelang.php?lang=es mimp3.net/changelang.php?lang=en and you can check if the language change in mimp3.net/old1 Only works when you make the change from: mimp3.net/indexz23.php
The GET method wasn't working because he had: $lang = $_GET['language']; But it should have been $lang = $_GET['lang];
